Okay, hmm.
Phrases like "don't judge a book by its cover."
Oh, the sentiment I totally agree with. It's the actual phrase: Of course you judge a book by its cover. That's the whole point. If I see a gorgeous special edition Complete Works of Shakespeare, I'm going to buy it; if I see a flimsy paperback that looks like the graphic designer/layout editor person didn't to their job right, I'm probably going to pass it by, if only because I don't want to have that blatant sin of a cover sitting on my bookshelf.
